Вариант 3. 1. Вычислите: a) arcsin (-1/√2) + arcsin 1 - arcsin √3/2;

\(\arcsin \left(-\frac{1}{\sqrt{2}}\right) = -\frac{\pi}{4}\)

\(\arcsin 1 = \frac{\pi}{2}\)

\(\arcsin \frac{\sqrt{3}}{2} = \frac{\pi}{3}\)

\(-\frac{\pi}{4} + \frac{\pi}{2} - \frac{\pi}{3} = \frac{-3\pi + 6\pi - 4\pi}{12} = -\frac{\pi}{12}\)
